restricted share unit financial

"Each restricted share unit (RSU) represents the contingent right"

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

vesting schedule financial

"subject to a four year vesting schedule"

A vesting schedule is a timeline that determines when someone gains full ownership of certain benefits, such as company stock or retirement contributions. Think of it like earning the right to own a gift gradually over time, rather than receiving it all at once. It matters to investors because it affects when they can fully access or sell these benefits, influencing their financial planning and decision-making.

contingent right financial

"represents the contingent right to receive one share"
